Official 2003 23&7/8 x 18" 25th Anniversary commemerative poster for the 12/31/1978 closing of Winterland in San Francisco, featuring the Grateful Dead appearing with the New Riders of the Purple Sage and the Blues Brothers.

 Art by (and signed and numbered 230/500 in silver ink by) Stanley Mouse and Alton Kelly, extra-thick high-gloss coated (Coventry Rag) stock poster is in beautiful mint/near mint to near mint (A/A- to A-) condition; just the slightest whisper of surface wear (a stray fingerprint smudge or two), otherwise it is an unbeatable DOUBLE-SIGNED example of this beautiful interpretation of the classic "Blue Rose" image.

 Additionally, this poster comes with a certificate of authenticity from Grateful Dead Productions.
